so standard turbo then ?

If so then in my opinion your flowing to much air to it, hence the jerkyness.

I've got a 20G turbo and got this 'stall' issue after fitting the HUGE APS725-DR FMIC.

I have learnt to drive 'around' the problem, doesn't bother me.

However, I would never fit a FMIC unless I had an uprated turbo to suit.

Good excuse to buy a bigger turbo then.
